LHS:

= 1+tan²A / 1+cot²A

= Sec²A/ Cosec²A

= Sin²A/Cos²A

= tan²A

RHS:

=(1-tanA)²/(1-cotA)²

=(1-sinA/cosA)²/(1-cosA/sinA)²

=[(cosA-sinA)/cosA]²

/ [(sinA-cos)/sinA)²

=(cosA-sinA)²×sin²A

/Cos²A. /(sinA-cosA)²

=1×sin²A

/Cos²A×1. ?? (-1)²= 1

=tan²A

Hence proved

Let me know if there are some corrections...Thanks!
